If you’re not smiling, make an attempt to do so.
Negative moods are caused by “stuck thoughts.” When that happens, get up for a few minutes and change your environment. Spend some time walking or call a friend or just breathe deeply. Change your focus – even if it’s only for a short time.
You’ll notice that your mood lifts almost immediately.
If you find that you’re frowning a great deal, remember even positive people need help at times. Reach out.
